Taizé receives large numbers of young people during the spring, summer and autumn, but in wintertime they encourage them to meet up in a city, and trust to the locals to find them room for sleeping mats (in houses, school gyms, church halls). "Pilgrimage of trust" is a phrase I've heard for it; perhaps even the official name. They've done one city after another for 30 years, and this year they're coming to Brussels, from 29 December to 2 January.
I've been asked to help organize the sleeping places in our parish and it's proving a slow business to find people willing to open their doors to foreign youngsters during the Festive Season. That it is the Festive Season is one of the most common reasons given for not doing - which makes me wonder what they can be celebrating in the dead of winter if it doesn't include hospitality. Belgians are also reluctant to provide floor space: those who are willing to take in strangers are those with spare beds. Saying that the pilgrims are only expecting floorspace scandalizes them. As I recently said to a Hungarian friend: the Belgians are the most hobbit-like people on the planet.
